and designed to include an overload factor of 25% to ensure minimum effort
to operate. A sealed and prelubricated ball bearing is present at the rotating
support point. (A torsion spring charge wheel is used for applying spring
torque and for future adjustments). Stainless steel or hot dipped galvanized
pipe assemblies are available. Option: High Cycle Springs can be designed to
